    copied!<p>I'm going to build a hotel table. But I'm having problems when trying to implement this in Java.</p> <p>My hotel has <strong>Level(<em>int id</em>)</strong> x <strong>Room(<em>int id</em>)</strong> x <strong>Field</strong>(<strong><em>String</strong> status, int counter</em>)</p> <p>The same <strong>in php</strong> would look like:</p> <pre><code>$level=1; $room=2; if(isset($hotel[$level][$room])) { print("Room: ".$level*100+$room); print(", Status: ".$hotel[$level][$room]['status']); print(", Total clients:".$hotel[$level][$room]['counter']); } </code></pre> <p>And this print returns me(if room exist): <em>"<strong>Room:</strong> 102, <strong>Status:</strong> Reserved, <strong>Total clients:</strong> 8";</em></p> <p>Now I want to have the same in JAVA.</p> <p>But the problem is, that I'm not able to build this:</p> <pre><code>int[][][] my hotel; </code></pre> <p>Because, I have the different types in my multi-dimensional array.</p> <p>I tried to make sth like this:</p> <pre><code>Map&lt;String, List&lt;String&gt;&gt; myHotel = new HashMap&lt;String, List&lt;String&gt;&gt;(); </code></pre> <p>Or:</p> <pre><code>List&lt;List&lt;List&lt;String&gt;&gt;&gt; myHotel; </code></pre> <p>But</p> <pre><code>out.println( myHotel.get(1).get(2).get("status") + "\n" + out.println(myHotel.get(1).get(2).get("status")); </code></pre> <p>Or even:</p> <pre><code>out.println("Status:" + myHotel.get(1).get(2).get(0) + "\tClients:" + myHotel.get(1).get(2).get(1) ); </code></pre> <p>Also how to put elements. I'm thinking about sth like: WHEN it's <strong>a MAP table</strong>:</p> <pre><code>myHotel.put(1).add(2).add(0, "Reserved")); // But better would be: // myHotel.put(1).add(2).add("status", "Reserved")); </code></pre> <p>Or WHEN it's <strong>a List</strong><code>&lt;List&lt;List&lt;String&gt;&gt;&gt;</code>:</p> <pre><code>myHotel.add(1).add(2).add(0, "Reserved")); // But better would be: // myHotel.add(1).add(2).add("status", "Reserved")); </code></pre> <p>Thanks for helping :)</p>
